Xabagta daweynta Epoxy UV waxaa si weyn loogu isticmaalaa beeraha dahaadhka korantada, daahan ka hortagga daxalka, xidhitaanka biraha iyo wixii la mid ah sababtoo ah xoogga isku xidhka sare, dusha isku xidhka ballaaran, hoos u hooseeya, xasilloonida wanaagsan, dahaarka korantada aad u fiican, xoog farsamo sare iyo habsocodka wanaagsan.Sanadihii la soo dhaafay, epoxy UV resin-ka daawaynta warshad ahaan ayaa kobcay.
Si kastaba ha ahaatee, wakhtigan xaadirka ah, caabbinta cimiladu inta badan alaabta epoxy waa mid daciif ah, gaar ahaan soo saarista xabagta epoxy, hogaanka dheriga dhoobada, epoxy UV daawoyinka xabagta dahabka ah ee xabagta, iwm., shuruudaha midabka alaabtu waa adag yihiin, taas oo sidoo kale horay u sii gelinaysa sare. Shuruudaha loogu talagalay waxqabadka huruud-diidka ee nidaamka epoxy.
Waxaa jira arrimo badan oo sababa jaallaha ah alaabta epoxy-ga: 1. Bisphenol-ka qaab-dhismeedka udgoonka epoxy UV ee daawaynta resin waa ay fududahay in la oksidhiye si loo soo saaro carbonyl si ay u sameeyaan koox jaale ah;2. Qaybta aminiga bilaashka ah ee wakiilka daawaynta amine waxa si toos ah polymerized leh epoxy UV resin daawaynaya, taasoo keentay kor u kaca heerkulka maxaliga ah iyo dardar huruud ah;3. Xawaareyaasha sare ee aminiga iyo dardargeliyayaasha nonylphenol way fududahay in la beddelo midabka oksijiinta kulul iyo shucaaca UV;4. Haddii heerkulku aad u sarreeyo inta lagu jiro falcelinta, wasakhda haraaga ah iyo kicinta birta ee nidaamka waxay keeni doontaa hurdi.
Xalka wax ku oolka ah waa in lagu daro antioxidant iyo ultraviolet nuugista, taas oo si wax ku ool ah uga hortagi karta oo dib u dhigi karta jaalaha.Si kastaba ha ahaatee, waxaa jira noocyo badan oo ka mid ah antioxidants, iyo xulashada alaabta ku habboon waxay u baahan tahay taageero farsamo oo gaar ah iyo ururin khibrad leh.
Kala soocida antioxidants: mid waa antioxidant-ka ugu weyn: qabashada peroxides free radicals, inta badan antioxidants phenol xannibay;Mid ka mid ah waa antioxidant kaaliyaha: decompose hydroperoxides, inta badan phosphite esters iyo thioesters.Guud ahaan, antioxidants kala duwan ayaa lagula talinayaa iyadoo loo eegayo habka wax soo saarka, alaabta ceeriin, dareerayaasha, wax lagu daro iyo buuxinta warshadeeyayaasha kala duwan, kuwaas oo marxaladda jaalaha ah iyo heerka jaalaha.
Iftiinka ultraviolet sidoo kale waa dembiilaha muhiimka ah ee keena huruuda oksaydhka ee nidaamka epoxy, badiyaa ka yimaada iftiinka qorraxda.Sidaa darteed, gaar ahaan macaamiisha alaabtoodu u baahan tahay in loo isticmaalo bannaanka, waxaan kugula talineynaa in lagu daro qadar gaar ah oo nuuga UV ah alaabta, taas oo si wax ku ool ah u nuugi karta UV iyo dib u dhigista jaalaha.Intaa waxaa dheer, isticmaalka ultraviolet iyo antioxidant waxay ciyaari karaan saameyn isku-dhafan, iyada oo saameynta 1 lagu daray 1 ay ka weyn tahay 2.
Dabcan, isticmaalka antioxidants iyo ultraviolet absorbers asal ahaan ma xallin karaan dhibaatada jaalaha ah, laakiin waqti cayiman iyo waqti gudahood, waxay si wax ku ool ah uga hortagi kartaa huruuda oxidation ee alaabta, sii midabka biyaha ee alaabta si hufan iyo hagaajinta darajada alaabta. .
